we are running a Lotus Notes Traveller-installation 8.5.2. For certain circumstances, we are unable to pgrade to version 9.0. However, we are interested to run a BES 10-Server against the Traveller 8.5.2.

To my understanding, the connection is based on the ctivesysn-protocoll which is included also in 8.5.2. So it should be possible to install and run BES10 with this version of traveller.

Has anyon had experience whether this is possible and are there any special hints how to configure either Traveller or BES 10 to make them talk to ecah other?

BB10 devices are not supported in the current release of Notes Traveler versions 8.5.3 Upgrade Pack 2 and lower. Support for BB10 devices is planned for the Notes Traveler 9 release scheduled for availability in March 2013.
